No picture in upper half of screen, normal at bottom

No picture, only thin lines on upper half of screen, bright band at middle about a half inch wide, and a normal picture in the lower half of the screen.. It started this for only a few minutes at a time at first, but now the problem stays and does not clear up.

Could be something as simple as a bad contact on one of the deflection yokes or other coils on the cathode ray tube - check the contacts on the circuit board where these coils are connected, resolder the pins or wires if the contact is bad, also check connector pins for any dirt or oxydation and clean if necessary.

LG 32LH30 LCD TV Problem


IMO Seriously for $119 it's not worth it.
However, it does sound like a capacitor problem
If you are "Serious" about fixing I'd find a TV repair Forum.
Else I'd go here and get a new one.

Tv not working


this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!

Blue tint and lines on screen.


Those lines sound like "retrace lines" and several things can cause them. The most common are shorts inside the picture tube and shorted semiconductors in the video driver circuits. They can also be seen if the blue screen voltage is too high or if someone has tampered with the screen voltage control.

Top half of screen black


The vertical circuit is going bad,this is the one in charge of opening the picture up and down,try taping on the side to see if the picture reacts ,if it does your set has a loose conection and the vertical IC will need to be resoldered only but if it does not react the IC will have to be replaced,if you are familiar with tv service this will give you a place to start but if you are not be safe and seek the help of a servicer,please let Us know how it goes.

SONY KV-27FV310: UPPER HALF OF SCREEN IS BLACK


You have a vert sweep problem and unless you know how to trouble shoot this cuircit bring it to a pro. I found out mostly in these sets that the vert output IC is bad.. Also sometimes the b+ filter cap off the fly is leaky and made the IC to fail. Another thing is Im surprised to hear you got a pic with the vert failure and a bright line in the pic!! This could be a big problem when the sets fixed so dont run it too long like this. It could burn a line all the way across the screen and you will see a dark faint line in your pic because of this. BE CAREFULL!!
